T 0 all whom it may concern:

Be it known that I, W'ILLIAM HUMPHREY PERRIN, of New Liskeard, in the district of Nipissing, Province of Ontario, Canada, having invented certain new and useful Improvements in Shocking Attachments for Binders, do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to improvements in shocking attachments for binders and the objects of my invention are to devise certain improvements in the shocking attachments invented by me and for which I have obtained United States Patent No. 806,283, dated December 5th, 1905, whereby the operation of the device may be rendered more simple and efficient; and it consists essentially of the improvements hereinafter specifically described in detail, and set forth in the accompanying specifications and drawmgs.

In the drawings, Figure l is a perspective view of the side portion of a grain binder of any ordinary construction, showing my attachment in place. Fig. 2 is a sectional view of the revolving part of the mechanism of the shaft upon which they revolve. Fig. 3 shows a perspective detail of the means for raising and lowering the forks.

In the drawings like letters of reference indicate corresponding parts in each figure.

Referring to the drawings, a is the table of the binder, down which the grain passes, while it is being formed into sheaves and tied bybthe knotting mechanism partially shown at c is the shaft supported by the standard (1 from the binder and which supports a plurality of forks e by means of double arms f and g. The upper arms of each pair are fixed from vertical movement while the lower arms are adapted to be intermittently lowered, thus causing the forks e to swing from a substantially horizontal position to a vertical position, dropping the sheaf h at the same time.

The mechanism for operating these double arms in the present application has been much improved upon, the mechanism I now employ consisting of a plate i vertically movable on the shaft 0 and having projecting arms 9' secured thereto, to which the arms 9 are pivoted. The arms f are pivoted to projecting lugs s on a rotatable block t carried by the shaft 0 and fixed from vertical movement thereon. The upper surface of this block is provided with a plurality of ratchet teeth a which are engaged by like ratchet teeth formed on the underside of a ratchet disk '1) which is oscillated by means of a suitable driving arm w pivoted thereto, the opposite end of which is connected to a crank so on the main driving shaft y of the binder.

A compression spring 3 abuts the top of the block 12 and a fixed collar 4 on the shaft,

- whereby the said block may always be held in contact with the plate 15. The late i has secured to the underside thereof a bracket having arms Z and m therein which extend downwardly and normally bear on the surface of a plate a fixedly secured to the shaft 0. This plate has, in one side, an aperture p formed and in the other side a slot 0, and be neath this aperture and slot cam plates 1" and q are formed integral with the plate a and designed to raise the arms Z and m upwardly when the said arms are rotated.

In operation the ratchet disk 12 is oscillated bvlmeans of the arm w and crank m. This rotates the block 6 carrying the armsf and g, normally in their raised position as shown in Fig. 1. As the sheaves are discharged from the platform a they will be caught on the forks e but when the arms 1 and m on the brackets come 0 posite the aperture 79 and slot 0, the brac et will sink, allowing the plate 7) to drop depressing the arm g and causing the forks to assume the position shown in Fig. 2 discharging the sheaves in the form of a shock.

Immediately after the discharge of the sheaf, the arms Z and m, through bearing on the inclined cam plates 1 and q will be raised upwardly moving the forks into their original position through the raising of the arm g. This operation is intermittently repeated, the sheaves being all discharged in the form of a shock at predetermined parts of the revolution.

What I claim as my invention is 1. The combination with a double arm supporting a fork of a vertically movable bracket connected to the lower arm, a fixed plate normally supporting the bracket in its uppermost position, and means on said late permitting the intermittent lowering o the bracket, and means for restoring the bracket to its normal position, as and for the purpose specified.

2. The combination with a double arm l supporting the plate and having two downsupporting a fork, of a vertically movable wardly extending arms, a plate on which the bracket connected to the lower arm, a fixed I said arms rest, having two slots therein, and 15 plate normally supporting the bracket in its cam plates on the side oisaid slots, as and 5 uppermost position and mean-s on said plate for the purpose specified.

ermitting the intermittent lowering of the l Signed at New Liskeard, in the Province of bracket and cam means for restoring the Ontario, Canada, this 19th day of August, bracket to its normal position, as and for the g 1907.
